TBI's can resonate as issues later on in life for anyone.
American Football players and even Rugby players have been known to get them or Chronic Traumatic Encephalopathy (CTE) as the result of repeated mild TBIs occurring over months or years playing.
As another example, I was in a near fatal rollover accident as a child and developed partially complex seizures in the left temporal 22 years later as an adult from that incident.
Pliers it is then... sigh
